Roof-mounted vehicle cargo EW complex
CVN “Choven-2” is a multi-channel electronic warfare system designed to counter UAVs across the maximum operational frequency range.
Its roof-box form factor enables universal installation on any vehicle equipped with standard roof rails.
The system can be used both while the vehicle is in motion and for the protection of stationary positions.
Choven is designed as a ready-to-deploy practical solution: fast installation, stable operation, and no compromise between protection effectiveness and crew comfort.
The system is developed on the basis of the bestselling product in the Shatro line, adapted specifically to the automotive roof-box format.
Protection across all relevant frequencies
Choven is optimized to counter the most common types of enemy UAVs and control links and is equipped with 14 signal-jamming modules:
- 320–420 MHz, 50 W
- 420–520 MHz, 50 W
- 520–620 MHz, 50 W
- 620–720 MHz, 50 W
- 720–850 MHz, 50 W
- 850–950 MHz, 50 W
- 950–1050 MHz, 50 W
- 2100–2300 MHz, 50 W
- 2300–2500 MHz, 50 W
- 2500–2700 MHz, 50 W
- 2395–2490 MHz, 50 W (horizontal polarization)
- 2395–2490 MHz, 50 W (vertical polarization)
- 5145–5255 MHz, 50 W (horizontal polarization)
- 5145–5255 MHz, 50 W (vertical polarization)
The system can be adapted to specific missions and operating conditions.

Stable reliability — the UNWAVE standard
A key technical feature is the individual DC-DC converter for each module, which:
- stabilizes voltage
- ensures full output power at any battery charge level
- eliminates performance drop during prolonged operation
Like all UNWAVE products, Choven is developed and manufactured in Ukraine with minimal use of imported components.
Core modules, assembly, and quality control are performed by UNWAVE’s in-house team in Ukraine.
User-friendly form factor for daily operation
Choven is housed in a vehicle roof-box format, providing several practical advantages:
- installation on standard roof rails
- no intrusion into the cabin or vehicle body
- preservation of a civilian vehicle appearance
- protected placement of all modules and antennas
If required, the Choven configuration can be adapted to a specific vehicle make and model.
During ordering, the UNWAVE team takes into account the mounting system and roof design to ensure fast and correct installation.
Seamless integration within the UNWAVE ecosystem
We recommend using Choven in combination with the Bashur UAV detection and video signal analysis system – another UNWAVE solution that enables automated protection upon UAV detection.
Bashur + Choven = automated defense:
- Bashur detects a threat →
- automatically activates jamming via Choven →
- notifies the operator via the control panel and transmits the intercepted video feed →
- the operator gains critical decision-making time while the system operates autonomously
At the same time, Choven remains fully effective in manual mode without the use of additional systems.
This makes it a universal solution — suitable both for integration into the UNWAVE ecosystem and for standalone deployment.
